climate change is 'our greatest threat in thousands of years'

British broadcaster and environmentalist David Attenborough on Monday urged world leaders, meeting in Poland to agree ways to limit global warming, to get on and tackle "our greatest threat in thousands of years".
Known for countless nature films, Attenborough has gained prominence recently with his "Blue Planet II" series, which highlighted the devastating effect of pollution on the oceans.
"Leaders of the world, you must lead," said the naturalist, given a "People's seat" at the two-week U.N. climate conference in the Polish coal city of Katowice alongside two dozen heads of state and government.
"The continuation of our civilisations and the natural world upon which we depend, is in your hands," he said.
The world is currently on course to overshoot by far the limits for global warming agreed in the landmark 2015 Paris accord on climate change, which were intended to prevent more extreme weather, rising sea levels and the loss of plant and animal species.
The Katowice talks are billed as the most important U.N. conference since Paris, coming ahead of an end-of-year deadline to agree a "rule book" on enforcing action.
Yet political and U.N. leaders have been struggling to inject urgency into two weeks of haggling on how to move on from fossil fuels to give practical effect to the Paris accord.
Representatives of some of the most powerful countries and biggest polluters were conspicuous by their absence, and the United States is quitting the U.N. climate process.
To maximise the chances of success in Poland, technical talks began on Sunday, a day early, with delegates from nearly 200 nations debating how to meet the Paris target of limiting global warming to between 1.5 and 2.0 degrees Celsius (2.7 and 3.6 Fahrenheit).
"Wave of Optimism Has Broken"
Michal Kurtyka, Poland's deputy environment minister and president of the talks, said that without success in Katowice, Paris would not be a success, as it had only decided what was needed, not how it could be done.

7 eating habits that we know are good for us:

1. Eat plenty of vegetables and fruits – Some countries are very specific about the number of servings of fruits and vegetables that we should consume daily, for example Greece says six, Costa Rica and Iceland say five. Canada even specifies the colors of vegetables to consume (one dark green and one orange vegetable a day). Serving sizes can vary by country; however, all guidelines recommend eating plenty of fresh vegetables and fruits on a daily basis.

2. Watch your intake of fats– Said in different ways, most guidelines make mention of reducing solid, saturated fats and give recommendations for replacing animal fats with vegetable oils. In Greece, olive oil is recommended, in Viet Nam it is sesame or peanut oil – demonstrating the importance of availability and cultural preference in each country’s guidelines.3. Cut back on foods and beverages high in sugar – It is generally agreed upon that processed sugar is harmful to our health. The guidelines in every country recommend to maint…

Humans are a massive minority on Earth. Why don't we act like it?

Humans are a massive minority on Earth. Why don't we act like it?

Most of us, including scientists, are blind to the full scope of the living world. This was illustrated by an informal survey which asked biologists and ecologists from elite universities two questions. In terms of mass, is the living world mostly composed of animals, plants or bacteria? And is there more global biomass on land or in the oceans? The majority of them answered both questions incorrectly.In an age of unparalleled access to information, this is a glaring gap in our knowledge. We are now equipped to close it. I joined colleagues from the Weizmann Institute in Israel and the California Institute of Technology to estimate the biomass of all kingdoms of life on Earth. The results were published in the journal of the American National Academy of Sciences, and were widely (and more digestibly) covered by the popular press.It required years of work, collecting and integrating information from hundreds of previ…

Chart of the day: These countries create most of the world’s CO2 emissions

With CO2 levels on the rise, being able to track global emissions is crucial. Image: REUTERS/Regis Duvignau Just two countries, China and the US, are responsible for more than 40% of the world’s CO2 emissions. With CO2 levels still on the rise, being able to track the global emissions hotspots is becoming more important than ever. Before the industrial revolution, levels of atmospheric CO2 were around 280 parts per million (ppm). By 2013, that level had breached the 400ppm mark for the first time. On 3 June 2019 it stood at 414.40ppm. Fifteen countries are responsible for more than two thirds of global CO2 emissions. Image: Visual Capitalist There are huge disparities between the world’s top 15 CO2 emissions-generating countries. China creates almost double the emissions of second-placed US, which is in turn responsible for more than twice the level of third-placed India.
